Description

Technical Field

[0001] This utility model relates to a base, specifically a prefabricated box-type substation switching base, belonging to the technical field of electrical equipment. Background Technology

[0002] Prefabricated box-type substations are widely used in power distribution systems due to their advantages of small footprint, short construction period, and ease of transportation and installation. To ensure the stability of the box-type substation during installation and its safety during operation, a base structure is usually required to support the box, adjust its level, and facilitate cable entry and exit. In existing technologies, the base of box-type substations is mostly a monolithic precast concrete structure or a non-adjustable welded steel frame. The installation process typically requires high precision in on-site construction. Furthermore, in actual construction, if the reserved space does not match the box dimensions, rework or on-site cutting and adjustment are often necessary, resulting in low construction efficiency and increased costs.

[0003] In addition, existing base structures have limited means of leveling and adjustment, especially in uneven foundation environments. There is a lack of auxiliary tools that can quickly determine whether each support point is on the same horizontal plane, which can easily lead to the installation of the box tilting, thereby affecting the stability of equipment operation and the reliability of subsequent cable connection.

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0026] In this invention, unless otherwise specified, all parts and percentages are by weight, and the equipment and raw materials used are commercially available or commonly used in the field. Unless otherwise specified, the methods in the following embodiments are conventional methods in the field. Unless otherwise specified, the components or equipment in the following embodiments are general standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0028] like Figure 1 and Figure 2 As shown, a prefabricated box-type substation interchange base includes a central column 1, four corner columns 2, and several connecting columns 3. Based on the bottom dimensions of the box-type substation to be installed, the required number of connecting columns 3 is determined in advance at the construction site. Subsequently, a foundation pit is excavated, and the four corner columns 2 are placed in a rectangular arrangement within the pit, corresponding to the four corner points of the substation. L-shaped first baffles 4 are provided at adjacent ends of the top of the corner columns 2, and the first baffles 4 are integrally formed with the corner columns 2, providing a structural foundation for reliable welding to the corner base of the box-type substation.

[0029] Between adjacent corner columns 2, connecting columns 3 are placed according to the actual spacing. Each connecting column 3 is equipped with a second baffle 5 at its top. The second baffle 5 is integrally formed with the connecting column 3 and is positioned facing away from the central column 1, for connecting to the central edge of the prefabricated substation. The number of connecting columns 3 is adjustable to accommodate the layout requirements of different types of prefabricated substations.

[0030] like Figure 3 As shown, the central column 1 is positioned at the center of the area enclosed by the four corner columns 2, enhancing the overall stability of the base. A cable entry port 6 runs through the center of the central column 1, allowing for cable insertion and installation during construction. For support, the bottom of the central column 1 is equipped with several legs 7, which are fixedly connected to the central column 1, ensuring good support even on uneven ground.

[0031] The central column 1, corner column 2, and connecting column 3 are all integrally cast. The first baffle 4 and corner column 2, and the second baffle 5 and connecting column 3 are integrally cast structures, ensuring the overall strength and dimensional accuracy of each connection. During the column casting process, the first welding plate 9, the second welding plate 10, and the third welding plate 11 are pre-embedded in the corresponding positions between the top of corner column 2 and the first baffle 4, between the top of connecting column 3 and the second baffle 5, and the top of central column 1, respectively. This ensures that each welding plate is firmly bonded to its corresponding structure, forming a stable welded connection foundation, which facilitates subsequent welding and fixing to the bottom of the prefabricated substation.

[0032] like Figure 4 and Figure 5As shown, the prefabricated box-type substation switchgear base also includes a leveling device 8, which is detachably mounted to the central column 1. Specifically, the leveling device 8 includes a connecting cylinder 801, a limiting plate 802, a rotating cylinder 803, several laser pointers 804, and a spirit level 805. The diameter of the connecting cylinder 801 matches the wire-passing port 6 and can be inserted into the wire-passing port 6 of the central column 1. The top of the connecting cylinder 801 is provided with a limiting plate 802, which is fixedly connected to the connecting cylinder 801; the top of the limiting plate 802 is equipped with a rotating cylinder 803, which can rotate relative to the limiting plate 802 to adjust the horizontal reference direction; the top of the rotating cylinder 803 is equipped with a spirit level 805 to determine whether the central column 1 is in a horizontal state. Several laser pointers 804 are provided at equal intervals on the outer edge of the rotating drum 803. The laser pointers 804 are all connected to the rotating drum 803. The lasers emitted by them can be directed to the leveling reference lines 12 on each corner column 2 and the connecting column 3 to assist in leveling and adjustment.

[0033] In actual construction, the operation steps are as follows: First, place the four corner columns 2 in a rectangular arrangement. Then, place connecting columns 3 between adjacent corner columns 2, and adjust their spacing according to the size of the box-type substation to achieve matching. Next, place the central column 1 in the center of the rectangle and insert the connecting tube 801 into the wire passage 6 of the central column 1. Observe the level 805 to determine whether the central column 1 is horizontal. If the central column 1 is horizontal, turn on the laser pointer 804 and rotate the rotating tube 803 to scan the top of each corner column 2 and connecting column 3 one by one, and observe whether the laser shines on the leveling reference line 12 on the corner column 2 or connecting column 3. If the laser is not at the leveling reference line 12, fine-tune the height and position of the corresponding corner column 2 or connecting column 3 until all the laser pointer 804 rays shine on the corresponding leveling reference line 12.

[0034] After the leveling operation is completed, the leveling device 8 is removed, and the cable is threaded through the cable entry port 6 of the central column 1. The prefabricated substation is then hoisted onto the base. The first baffle 4, the second baffle 5, and the pre-reserved welding points at the bottom of the box are aligned. A first welding plate 9 is installed between the top of the corner column 2 and the first baffle 4, and a second welding plate 10 is installed between the top of the connecting column 3 and the second baffle 5. A third welding plate 11 is installed on the top of the central column 1. The first welding plate 9, the second welding plate 10, and the third welding plate 11 are welded and fixed to their corresponding structures, completing the overall connection between the box and the base, thereby ensuring a firm installation, accurate leveling, and smooth wiring.

[0035] The implementation principle of this utility model of a prefabricated box-type substation interchange base is as follows:

[0036] A rectangular support frame is formed by the adjustable combination of four corner columns 2 and several connecting columns 3, with a central column 1 set at the center of the frame as the core of structural stability, thus adapting to the bottom structure of box-type substations of different sizes. A leveling device 8, inserted into the cable passage 6 of the central column 1, determines the horizontal state of the central column 1. Using a laser pointer 804 in conjunction with leveling reference lines 12 set on the corner columns 2 and connecting columns 3, the overall frame's horizontal state is calibrated and adjusted at multiple points, ensuring the stability and levelness of the box-type substation after installation. After installation, the box-type substation is firmly connected to the central column 1, corner columns, and connecting columns 3 using the first welding plate 9, the second welding plate 10, and the third welding plate 11, ensuring overall structural strength, convenient installation, and easy cable routing.

[0037] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
